This collection is comprised of a memorial book filled with handwritten condolences, memorials, and prayers for the victims of the mass shooting that occurred on October 1, 2017 at the Route 91 Harvest music festival in Las Vegas, Nevada. From October 2-10, 2017, Steve Round watched over a memorial that spontaneously developed in the median of Las Vegas Boulevard near the site of the shooting. Round invited visitors at the memorial, including families and friends of the victims, community members, first responders, and tourists, to sign the book.

The Association of Women in Science, Las Vegas, Nevada Chapter Records date from 1976 to 1999 and cover DeLyle Eastwood's effort to create a local chapter of the Association of Women in Science (AWIS), the completion of this goal, and the proceedings of the Las Vegas AWIS chapter. The mission of the chapter was to help women in science career fields, both in the industry and university setting, achieve success in their fields. The AWIS also held seminars to spark early interest in science for young girls. The collection contains chapter correspondence, newsletters, and mentoring materials.
